An appeal hearing for a group of men from the former Soviet Union (R) gets underway at Libya's Supreme Military Court in Tripoli May 29, 2013. A Libyan military court last year handed down long prison terms to the men accused of serving as mercenaries for ousted leader Muammar Gaddafi in the 2011 conflict.
